Model United Nations (MUN) is a pupil-led simulation of the real United Nations and gives young debaters an opportunity to engage with the key international issues of the day. Hamptonians from across the year groups meet once a week to discuss and provide solutions to a breadth of topics facing the world today.

Pupils also have the opportunity to attend real-world MUN conferences which run throughout the academic year. At an MUN conference, pupils work as the representative of a country or organisation, and must solve topical problems with other delegates.
